Called "House K", the structure is almost 30-feet-high and holds 1,700 feet of living space.

At its most narrow, a normal adult could almost touch both walls at once. Because space is at a premium, the architects had to come up with other clever ways to imitate the feeling of wide open space.

The house has two halves—one is slender and one is a bit chubbier, and the doorways that connect each side are open and breezy, without any doors.

In addition to being a clever demonstration of modern design, House K is also a demonstration of the future of the residential space. Designed to act as a duplex without walls, this space-efficient house could act as a prototype for cooperative living arrangements that build community without sacrificing privacy.
